04/2005 | Biomedizinische Technik, Walter de GruyterA fuzzy-augmented Kalman filter for IMU/GPS integration
Most of the present techniques for integrating Inertial Measurement Units (IMU) and Global Positioning Systems (GPS) utilize Kalman filtering (KF) as the integration estimation technique. KF is a recursive algorithm designed to compute corrections to a system based on external measurements. In inertial navigation, this can be accomplished by using an external navigation reference such as GPS. As long as GPS measurements are available, the KF solution of IMU/GPS integration works efficiently and provides accurate estimate of the navigation states...
